Should I Repair or Replace My HVAC System?

As a Southeast Michigan homeowner living in Ann Arbor or nearby communities, knowing whether it’s time to have your heating and cooling system repaired or replaced can be a real dilemma – particularly in an emergency situation.  While there is no one certain issue that determines which you should do, we have a few considerations we feel are essential in making your decision.

  • Age.  On average, most heat pumps and air conditioning systems last for about 10 to 12 years; furnaces tend to perform well for a bit longer, typically 15 to 20 years.  If your heating and cooling equipment falls within these general guidelines, expect to face more frequent repairs in the near future.
  • Outdated technology.  Technology is ever-changing today, not only with HVAC systems but smartphones and other appliances and equipment.  While it seems technology advances so fast it’s hard to keep up with the changes, replacing old heating and cooling equipment in your SE Michigan home will increase efficiency, save money on energy costs, and allow you to take advantage of the latest “smart” new features.
  • Repair costs.  When is it time to replace?  Consumer Reports advises home owners to replace a product or equipment when the cost of repairs exceed half (50%) of the cost of new equipment.  Also consider current promotions frequently offered by Lennox® dealers, which could save you even more when upgrading your heating/cooling system.
  • Tax credits.  In many cases, homeowners who invest in high-efficiency HVAC systems are eligible for both local and state tax credits.  Through 2016, those who purchase the SunSource® Home Energy System may qualify for a federal tax credit as well.
  • Size/capacity of your heating & cooling system.  There are many factors which may affect how energy efficient your home is aside from your HVAC system.  These include quality insulation, roofing, new windows, and more.  Depending on your situation, in may be to your advantage to downgrade to a smaller system, improving comfort while enjoying reduced operating costs.
  • Utility rebates and credits.  Often, replacing an older heating & cooling system with a modern, higher efficiency model allow homeowners to take advantage of incentives offered by local utility companies for upgrading.  Not only may you quality for credits and one-time rebates, you will also experience substantial savings on utility costs each month.  To learn about credits and/or rebates available in southeast Michigan, visit or contact your local utility company.
  • Environmental impact.  Many homeowners are concerned about their environmental footprint, and how it may affect future generations.  You may or may not be aware that heating and cooling systems are responsible for approximately 50% of the energy consumed in your home.**  You can rest assured that your system meets or exceeds federal energy efficiency standards by upgrading to ENERGY STAR® qualified equipment.

Does your heating and cooling system perform well?  If the air inside your home feels damp, stuffy, or you find yourself adjusting the thermostat constantly to remain comfortable, it may be time for an upgrade.  This may also be the case if your furnace or air conditioner makes strange or unusual noise upon start-up.
